BACKGROUND: The association between Executive Function (EF) and Theory of Mind (ToM) in autism spectrum disorder (ASD) has been mainly investigated using false belief tasks, whilst less is known about the EF effect on other ToM facets. Furthermore, the role EF plays in social communication in ASD is mainly assessed using parent-report EF ratings rather than direct assessment. AIMS: The aim of this study was to shed more light on the effect of performance-based EF measures on ToM and social communication in middle childhood in ASD relative to neurotypical controls...

Exfoliation syndrome (XFS) is an age-related disease involving the deposition of aggregated fibrillar material (XFM) at extracellular matrices in tissues that synthesize elastic fibers. Its main morbidity is in the eye, where XFM accumulations form on the surface of the ciliary body, iris and lens. Exfoliation glaucoma (XFG) occurs in a high proportion of persons with XFS and can be a rapidly progressing disease. Worldwide, XFG accounts for about 25% of open-angle glaucoma cases. XFS and XFG show a sharp age-dependence, similarly to the many age-related diseases classified as aggregopathies...

The ability of proteins to spontaneously form their spatial structures is a long-standing puzzle in molecular biology. Experimentally measured rates of spontaneous folding of single-domain globular proteins range from microseconds to hours: the difference - 10-11 orders of magnitude - is the same as between the lifespan of a mosquito and the age of the Universe. This review (based on the literature and some personal recollections) describes a winding road to understanding spontaneous folding of protein structure...

This study tests specific competing hypotheses from social dominance theory/realistic conflict theory (RCT) versus system justification theory about the role of social status. In particular, it examines whether system justification belief and effects are stronger among people with low socioeconomic status, and in less socially developed and unequal nations than among better-off people and countries. A cross-national survey was carried out in 19 nations from the Americas, Western and Eastern Europe, Asia, and Oceania using representative online samples ( N = 14,936, 50...

This qualitative study explored the cultural identity negotiation of young adult immigrants. Using a grounded theory research design, 10 semistructured interviews were conducted with emerging adult immigrants (EAI), ages 19-27. Results yielded a substantive model of cultural identity negotiation (MCIN) for EAI and posited that One's Motivation and Sense of Agency to Negotiate Cultural Identity is at the core of how participants navigate their cultural identities. This model included 6 major categories: (a) Family Cultural Rigidity ; (b) Connections Specific to Canada ; (c) Connection to a Same Cultured Community ; (d) Sense of Permanency ; (e) Desire to Preserve Culture of Origin ; (f) Desire to Fit in to Canadian Culture , as well as 2 overarching factors ( Dimension of Time and Dimension of Age ), which were found to be influential on participants' cultural identity negotiation...

INTRODUCTION: Low-income caregiver perspectives on asthma management are understudied but may illuminate strategies to improve care delivery and child outcomes. METHOD: Purposive sampling methods were used to recruit 15 caregivers of children with frequent asthma emergency department visits. Interviews explored how poverty and stress affect asthma management. Grounded theory coding techniques were used to analyze the data. RESULTS: Participants were the biological mother (100%) and were poor (75% had mean annual income ≤ $30,000)...

Although parenting behavior and friendship quality predict adolescent externalizing behaviors (EBs), individual differences in temperament may differentially affect susceptibility to these factors over time. In a multi-method and multi-informant study of 141 children followed prospectively from toddlerhood to adolescence, we tested the independent and interactive associations of age 3 reactive temperament (e.g., negative emotionality) and age 13 observed parenting (i.e., positive and negative behavior) and friendship (i...

We investigated the longitudinal associations between self-reported aggression, self-perceived social status, and dating in adolescence using an intrasexual competition theoretical framework. Participants consisted of 536 students in Grade 9 (age 15), recruited from a community sample, who were assessed on a yearly basis until they were in Grade 11 (age 17). Adolescents self-reported their use of direct and indirect aggression, social status, and number of dating partners. A cross-lagged panel model that controlled for within-time covariance and across-time stability while examining cross-lagged pathways was used to analyze the data...

Cognitive impairment caused by subcortical ischemic vascular disease (SIVD) has been elucidated by many neuroimaging studies. However, little is known regarding the changes in brain functional connectivity networks in relation to the severity of cognitive impairment in SIVD. In the present study, 20 subcortical ischemic vascular cognitive impairment no dementia patients (SIVCIND) and 20 dementia patients (SIVaD) were enrolled; additionally, 19 normal controls were recruited. Each participant underwent a resting-state functional MRI scan...

Background: When considering the "joint as an organ", the tissues in a joint act as complementary components of an organ, and the "set point" is the cellular activity for homeostasis of the joint tissues. Even in the absence of injury, joint tissues have adaptive responses to processes, like aging and menopause, which result in changes to the set point. Purpose: The purpose of this study in a preclinical model was to investigate age-related and menopause-related changes in knee-joint tissues with the hypothesis that tissues will change in unique ways that reflect their differing contributions to maintaining joint function (as measured by joint laxity) and the differing processes of aging and menopause...

This article presents moderating influences, one of the sub-core categories from the theory of accommodating interruptions. This theory emerged in the context of young people who have asthma, explaining how they develop behaviours in their everyday lives (Hughes 2014; Hughes et al., 2017). The aim of this research was to develop a theory on the behaviours of young people who have asthma, in relation to the impact of asthma on the lives and the issues affecting them. This research was undertaken using a classic grounded theory approach...

This paper analyses the interference of three socio-demographic characteristics: gender, age and migration status on the labour market outcomes from the perspective of intersectionality theory. Concretely, we investigate whether gender and migration differences in hourly wages are observable at younger ages and whether these differences increase with age. Further, we analyse whether gender and migration interact in such a way that women with migration background suffer lower wage growth in relation to their counterparts...

Human adults recruit distinct networks of brain regions to think about the bodies and minds of others. This study characterizes the development of these networks, and tests for relationships between neural development and behavioral changes in reasoning about others' minds ('theory of mind', ToM). A large sample of children (n = 122, 3-12 years), and adults (n = 33), watched a short movie while undergoing fMRI. The movie highlights the characters' bodily sensations (often pain) and mental states (beliefs, desires, emotions), and is a feasible experiment for young children...

BACKGROUND: The incidence of vulvar cancer is increasing, but surgical treatment-the current standard of care-often leads to unsatisfactory outcomes, especially in patients with node-positive disease. Preliminary results at our centre showed that locoregional spread of vulvar carcinoma occurs within tissue domains defined by stepwise embryonic and fetal development (ontogenetic cancer fields and associated lymph node regions). We propose that clinical translation of these insights into practice could improve outcomes of surgical treatment of vulvar cancer...

BACKGROUND: Results from studies evaluating the effectiveness of focused psychosocial support interventions in children exposed to traumatic events in humanitarian settings in low-income and middle-income countries have been inconsistent, showing varying results by setting and subgroup (eg, age or gender). We aimed to assess the effectiveness of these interventions, and to explore which children are likely to benefit most. METHODS: We did a systematic review and meta-analysis of individual participant data (IPD) from 3143 children recruited to 11 randomised controlled trials of focused psychosocial support interventions versus waiting list...
